Indications to do this procedure are: unexplained chronic abdominal pain with weight loss, unexplained diarrhea, anemia which is caused by gastrointestinal bleeding or dependent on blood transfusion where the cause cannot be explained despite OGDS or colonoscopy investigations, partial obstruction of bowel/small bowel adhesive obstruction ...
Chromoendoscopy is a medical procedure wherein dyes (often the same stains used in histology) are instilled into the gastrointestinal tract at the time of visualization with fibre-optic endoscopy. The purpose of chromoendoscopy is chiefly to enhance the characterization of tissues, although dyes may be used for other functional purposes. The ...
After the scan is complete, the patient is encouraged to eat and drink normally, with special attention to plenty of fluids. The barium sulfate is excreted through defecation , so extra fluid intake helps prevent constipation , which is a possible side effect (see Johns Hopkins Medicine Health Library for an example of a possible patient ...
A lower gastrointestinal series is a medical procedure used to examine and diagnose problems with the human colon of the large intestine. Radiographs (X-ray pictures) are taken while barium sulfate, a radiocontrast agent, fills the colon via an enema through the rectum.
The radiologist measures the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal. The test can help confirm a diagnosis of dumping syndrome. The health care provider may also examine the structure of the esophagus, stomach, and upper small intestine with the following tests: [1] An upper GI endoscopy to see the
Hemosuccus pancreaticus is a rare cause of hemorrhage in the gastrointestinal tract.It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine.
A double-contrast barium enema is a form of contrast radiography in which x-rays of the colon and rectum are taken using two forms of contrast to make the structures easier to see. [1] A liquid containing barium (that is, a radiocontrast agent ) is put into the rectum.
The subject drinks 1.5 litres of oral contrast (3% mannitol) [3] over 30 to 45 minutes before the scan. After that venous access is obtained and Buscopan (hyoscine butylbromide) is given to reduce the gastrointestinal tract movement, thus reducing motion artifact on MRI scan. [4]
